Introduction

In mathematics, evaluating sums is a fundamental concept that involves finding the total value of a series of numbers. In this article, we will evaluate the sum $\sum_{n=1}^4 \frac{k}{n+1}$. This sum involves a variable $k$ and a series of fractions. Our goal is to simplify the sum and find its value.

Understanding the Sum

The given sum is $\sum_{n=1}^4 \frac{k}{n+1}$. This sum can be written as:

$$\sum_{n=1}^4 \frac{k}{n+1} = \frac{k}{1+1} + \frac{k}{2+1} + \frac{k}{3+1} + \frac{k}{4+1}$$

Simplifying the Sum

To simplify the sum, we can start by evaluating each fraction individually.

$$\frac{k}{1+1} = \frac{k}{2}$$

$$\frac{k}{2+1} = \frac{k}{3}$$

$$\frac{k}{3+1} = \frac{k}{4}$$

$$\frac{k}{4+1} = \frac{k}{5}$$

Now, we can substitute these values back into the original sum.

$$\sum_{n=1}^4 \frac{k}{n+1} = \frac{k}{2} + \frac{k}{3} + \frac{k}{4} + \frac{k}{5}$$

Conclusion

In conclusion, the sum $\sum_{n=1}^4 \frac{k}{n+1}$ can be simplified to $\frac{k}{2} + \frac{k}{3} + \frac{k}{4} + \frac{k}{5}$. This is the final value of the sum.

Answer

The correct answer is:

• A. $\frac{k}{2}+\frac{k}{3}+\frac{k}{4}+\frac{k}{5}$

Discussion
